The Lightning Beetle is an insectoid creature that is about the size of a fist. It has a dark blue exoskeleton that seems to shimmer in the light, with a pair of small wings and six legs that allow it to move quickly and climb up walls and other surfaces. 

Despite its fearsome appearance, the Lightning Beetle is not typically aggressive and tends to avoid conflict whenever possible. It spends most of its time scurrying around dark, damp areas like caves, ruins, or other places that are likely to harbor insects or other small creatures it can prey upon.

When threatened, the Lightning Beetle will attempt to intimidate its attacker by flashing its bright light and emitting sparks of electricity. If that doesn’t work, it will resort to biting and using its powerful lightning blast to defend itself.

Live beetles are often collected by gnomes and artificers to power mechanical contraptions. The carapaces of dead beetles can be ground up and used as an ingredient in a Potion of Lightning Breath.
